Astronomers find one of the oldest stars in the Universe The other star we've found so far has so little iron -- a key indicator that it was forged close to the dawn of the universe. But earlier estimates from observations dating back to 2000 placed the star as old as 16 billion years. An explosion of high-energy radiation may have been spotted coming from a galaxy in the distant universe. Once a star goes supernova, the explosion sends its elements across the universe, making them the building blocks of new star formations. That makes it the oldest object ever observed. Constellation:  Aquarius. Since SMSS J160540.18–144323.1 has a … Constellation:  Boötes. This makes it among the oldest stars and nearly as old as the estimated age of the universe itself (13.8 billion years as measured by Planck). Type:  Red giant Save my name, email, and website in this browser for the next time I comment. 200 million years after the Big Bang, the very first stars (called Population III stars) began to form, researchers discovered seven new neutron-capture elements in HD 122563, Frebel used the ESO’s VLT to measure the abundance of the radioactive elements uranium and thorium in HE 1523-0901, a group of scientists discovered that BD +17° 3248 had gold, star could be as old as 14.5 billion years. As part of new research, astronomers tried to find the oldest star. BPS CS22892-0052, which is called Sneden’s Star after it’s lead observer Chris Sneden from the University of Texas at Austin, is another ancient star in the galactic halo of the Milky Way. It is about 13 billion years old and was discovered using the Curtis Schmidt telescope at the Cerro Tololo Inter-American Observatory in Chile. Age:  13.6 billion years The oldest staris located in the southern part (15:23-0901) of Constellation Libra, the Scales of Justice — south of Mu Serpentis and north of Gamma Librae. Distance from Earth: ~4,140 light years Type:  Subgiant While all Population II stars are metal-poor, this star is considered extremely metal-poor. Once the star becomes a supernova, the explosion spreads the elements throughout the Universe, turning them into building blocks of the new star formations. About 200 million years after the Big Bang, the very first stars (called Population III stars) began to form. Although another star on this list was known for being the most metal-poor, Caffau’s Star now has this title. Methuselah Star, the Oldest Known Star in the Universe. HE 1523-0901 is the oldest known star in our galaxy, the Milky Way. Researchers say that the star could be as old as 14.5 billion years, but this would make it older than the calculated age of the universe, which is about 13.8 billion years old. HD 140283 (or the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Age:  13 billion years Among stars found in the Milky Way, it has the lowest iron level ever measured. Distance from Earth: 15,300 light years Constellation:  Libra. Astronomers have discovered the oldest living star in the (known) universe — and, remarkably, it’s situated right on our galactic doorstep, just 6,000 light years away, well within the Milky Way. Age:  ~14.5 ± 0.8 billion years (at least 13.2 billion years) Caffau said that she was surprised to actually find a star in the “forbidden zone” of the star formation model. However, recent calculations have lowered the star’s age to at least 13.2 billion years, which overlaps with the universe’s age. photo source: astronomynow.com SXDF-NB1006-2, another distant galaxy from the early days of the universe, was discovered in 2012 by scientists using the Subaru and Keck telescopes.Like all the other galaxies on this list, at the time of its discovery, SXDF-NB1006-2 was the oldest known galaxy in the universe.

HE 1523-0901 is the designation given to a red giant star located in the Milky Way galaxy approximately seven and a half light-millennia from Earth. Stars are grouped into three populations, I, II and III How old are the oldest stars in the Universe? The star is made almost entirely out of helium and hydrogen, with an extremely low amount of other chemical elements. Methuselah Star in the constellation of Libra is believed to be the oldest star in the universe, born soon after the creation of the Universe. After the Big Bang, the Universe was warm enough, so the formation of neutral hydrogen, the main material of stars, was impossible. While Population III stars have yet to be detected by scientists, the oldest known stars that have been observed were born after the first stars went supernova. The star belongs to a class of stars known as ultra-metal poor stars, specifically the rare subclass of neutron-capture enhanced stars. Previously, the title of oldest known star in the universe was held by HD 140283, which is about 13.2 billion years old. The researchers said that while every star probably has trace amounts of gold, this was the first time that they were able to confirm the element’s existence. The newfound star is not only one of the oldest stars in the universe, but also one of the most metal-poor stars known. Since about 1995, researchers led by Chris Sneden have found an abundance of 53 chemical elements in the star, which is second in number to the Sun. These are recognized as among the oldest: Some of these are among the first stars from reionization (the stellar dawn), ending the Dark Ages (cosmology) about 370,000 years after Big Bang. Type:  Unknown This star formed so early in our Universe’s history, was most likely a second-generation star. HD 122563 is unique among the other earliest known stars. Which is our universe's oldest star? Required fields are marked *. They added that because of BD +17° 3248’s age, this gold is representative of the first gold made in the universe.
